A Camp Lejeune Marine and a Michigan man are accused of working together to sell large amounts of marijuana to Camp Lejeune Marines.

Dustin Kauffman, 35, of Jackson, Mich., was arrested over the weekend for selling marijuana to Camp Lejeune Marines after the local Marine was arrested for selling marijuana and NCIS investigators tracked his supplier to Michigan. The Marine, whose name is not being released by investigators at this time, spent the last year and a half making three road trips a month to Michigan to buy the marijuana and bringing it back to sell to other Marines on the base.

Special Agent Joe Kennedy of the Camp Lejeune Naval Criminal Investigative Services said they are expecting to make more arrests, and releasing the Marine’s name could jeopardize the case.

After arresting the Marine — who was allegedly buying marijuana from Kauffman for $3,200 a pound — NCIS investigators went to Jackson, Mich. and worked with local law enforcement, as well as the Drug Enforcement Administration, to seize 311 marijuana plants worth $995,200 in searches of Kauffman’s five Michigan homes over the weekend, according to investigators.

“It was a great overall team effort by the Michigan state police, our office and the DEA,” Kennedy said.

Investigators found an elaborate grow operation that included plants growing in water instead of soil — a method that creates a more potent form of the drug, said Detective Lt. Dave Cook, of the Jackson Narcotics Enforcement Team in Michigan.

Investigators said Kauffman had converted each of his five homes into a grow room, using his own ventilation and irrigation systems.

“It’s probably the most elaborate (grow system) I’ve ever seen,” said Cook. “Just the way the plants were set up and the grow rooms and the irrigation system ... He told our investigators he had over $50,000 in grow equipment.”

Kauffman was arraigned Tuesday in Michigan state courts and charged with delivering or manufacturing more than 45 kilograms of marijuana or more than 200 marijuana plants. Investigators say they also found two guns — a shotgun and a handgun — hidden in one of his homes and have charged Kauffman with using a firearm to commit a felony.

Kauffman is currently being held on a $100,000 bond and may also face federal charges for selling to Marines, Cook said.
